Application filed September 10,1312. Serial N 9.719327.

To all whom itmay concern:

Be it known that I, JAMns A. Poem, a

citizen of the United States, residing at. Viaxahachie, in the county of Ellis and State of Texas, have invented new anduseful Improvements in Pneumatic Tires and Armors.

Therefor, of which the following is a specification.

This invention relatesto pneumatic tires and armors therefor, the object of the invention being to provide a construction of tire and armor which permits 'of the firm retention of the armor in position and protec tion of the tire against possibility 'ofpuncture of the tread thereof, the ready and convenient placing of the armor in position and renewal of its tread portion when occasion requires, and a. free and unrestricted movement of the armor so as to allow the tire to have ample resiliency.

. of one of the links. Fig. is a side view of one of the clamping plates. Fig. -6 is a top plan view thereof.

Referring to the drawing, 1 designates a pneumatic tire of any suitable type, and which in accordance with my invention is provided with a thickenedoifset tread ortion 2 having a transversely convexe or 'w rounded upper face -3 and substantially straight and parallel side edges or abutment shoulders 4. -The inner face ofv thetread surface of the tire is formed atfriitableintervals with concave seats orflebesses 5 andbolt holes 6 communicating therewith;

Surrounding the tread portion of the tire ment under the contraction'and expansion of the .tire. The sides of the rim sections or segments are formed with recesses 10 receiving (the enlarged" approximately circular end portions of links 11 which fit freely therein andlare 'pivotally secured to the sections by countersunk screws 12, whereby all the sections are pivotally coupled together to form a freely movable link band.

The sections of the band are formed in their upper. faces with channels 13 and in their lower faces with channels 14, which latter receive and embrace the thickened tread and provide abutment flanges 15 on gaging the abutment surfaces 4 of the tread, thus holding the guard iii/position against lateral' st-rain'and possibility of displacement. The channels 13 of the rim sections are in accurate alinement and receive a tread or wear surface 16 of rubber or other suit able elastic material, and-which may be provided with a corrugated or roughened periphery. for. contact with the ground. This tread or wear surface 16 may be removed when worn and a new one substituted therefor without the necessity of detaching the rim from the tire.

The flexible, rim is secured to the tire at suitable intervals by fastening devices each comprising a segmentally curvedelclamping plate 17 having a screw stem or bolt 18 projecting therefrom and receiving aclamping nut 19. The plates 17 fit within the recesses 5, and the bolts 18-project through the openings 6 in the tread 2 and receivethe nuts 19, which bear upon the inner wall ofthe channels of the'rim sections and thus clamp the rim in position against possibility of creeping orshifting movement on the tire or of radial outward displacement there from. The nuts and projecting ends of the bolts 18 fit within recesses 20 formed in the inner surface of the tread 16.

From'the foregoing description, taken in connection with the drawings, it will be seen that a-construction of rim is provided which is freely flexible with the tread portion ofthe tire,and that the construction ofthe'latte-r permits of the firm retention of the fiexi ble rim section in position, the tread surface of the tire thus being guarded against penetration, While permitted to move freely to give the desired cushioning resiliency. Also it will be seen that the construction described permits of the ready substitution of new treads 16 for old ones-when the tread in use becomes worn from service;

nner face of the rim band receiving and em r romeo? I claim I A tire haying anoffset or thickened tread portion provided with a central concavity in the underside thereof, a flexible rim band surrounding the tire and channeled upon its inner.-' =sind outer faces, the said channeled bracing said thickened tread portion, said rim band consisting of a series of sectionshaving rounded contact portions and partially circular recesses in the sides thereof and links havin partially circular end portions seated an pivotally mounted in said recesses, a resilient tread seatedin theouter channel of the rim band, concave-convex 5 and rim, and nuts engaging said bolts and 20 drawing said plates in clam ing position.
